SPECIFICATION forming part of Letters Patent No. 673,038, dated April 30, 1901.

Application fled August 18, 1899. Serial No. 727,645. (No model.)

To all whom it may concern:

Beit known that I, CHARLES THERYC, a citizen of the Republic of France, residing at Marseilles, France, have invented new and useful Improvements in or Relating to Motors, which are fully set forth in the following specification.

This invention relates to an improved motor device or compound generator and motor.

In order that the following explanation may be rendered as clear as possible, a construction of the improved apparatus is represented, by way of example,in the accompanying drawings, in which- Figure 1 is a vertical section along the axes of the shafts. Fig. 2 is a broken section perpendicular to the axes of the shafts. Fig. 3 is a section in plan on the line A B of Fig. l. Fig. 4 is a section in plan on the line C D of Fig. 2. Fig. 5 is a sectional view of the differential Valve.

The compound generator and motor comprises, irst, a compression and explosion cylinder a, in which the combustion of the Yexplosive mixture is effected; second, a reservoir d, surrounding the driving-cylinders and in which is stored under pressure the combustion-gases, as will be explai-ned farther on, and, third, two driving-cylinders b and c, in which the expansion and work of the gases are effected.

The apparatus operates in the following manner: The piston of the compressor andN explosion cylinder a, Fig. 1, draws throughy a passage 3a, controlled by an automatically# acting valve 3, Fig. l, carburet-ed air or explosive mixture, which it subsequently compresses and the explosion of which is eected4 by an Aelectric or other igniter m, Figs. 1 and 4. Under the effect of the expansion and of the strong pressure of the gases subsequent upon the explosion a differential valve 5, Figs. 2 and 5, which normally closes communication between the compressor and explosion cylinder a and the reservoir d, which are connected by a pipe h, Fig. 2, opens automatically and admits the larger portion of the gases resulting from the combustion into this reservoir. The essential function of this Valve is to prevent the explosive mixture during its compression from entering this reservoir d and to only admit the same after its combus# tion. This valve, which is represented in section, Fig. 5, comprises a pump-body 8 7 6, connected with the reservoir d, Fig. 2. The part 7 6 of this valve forms a siphon and contains oil, above which is a small piston 6y which actuates the valve 5 by a lever-arm n, held in position by a balance-spring n. As

the power of this spring is so adjusted as to be greater than the pressure resulting from the previous compression of the explosive mixture and smaller than the far more energetic pressure resulting from the explosion, the valve 5 in its' position indicated in the drawingswill prevent the explosive mixture from entering the reservoir at the moment of compression and will only permit the gases burned in the explosion to enter; but in proportion as the reservoir d lillsand arrives at the desired pressure this pressure acts upon the liquid, and consequently upon the piston in the Siphon 7 6, which then lifts the lever n, connected to it, and the valve 5 is thus set free, and, being then only maintained upon its seat by the pressure in the reservoir d, exerted through the conduit h upon its upper face, itV

continues to act without the aid of the lever n, and hence it follows that the result aimed at is in all cases attained. The piston of the compressor and explosion cylinder a under the impulse of the explosion subsequently moyes outward and inward under the force acquired by the ily-wheels, causing those gases which have not been able to enter the reservoir to be expelled. At the same time an appropriate quantity of water is injected by a pump or in any other way' through an admission-port la, Fig. 2, and this Water becomes vaporized inv contact with the walls of the compressor and Vexplosion cylinder a while circulating in the spiral conduit 2 around said cylinder. This circulation of the water may be prolonged, as by causing it to flow in the cylinder bottom or cover and around the valves. The steam thus generated passes into the chamber 5a of the differential valve 5, wherein it is intimately mixed with the gases forced by the explosion and, while becoming superheated in contact therewith, lowers the temperature of the said' gases to a normal degree. The mixture resulting therefrom passes through the conduit h, Fig. 2, into the reservoir d, where it is stored, ready to act and to expand alternately in the loo driving-cylinders b and c by the action of suitable slide-valves e and f. It is introduced through a conduit or pipe g, which terminates at the top of a second spiral conduit l around the compressor and explosion cylinder a. This second spiral conduit is provided around the cylinder a, side by side With the first-mentioned conduit 2,and terminates in a distributing-chamber Z, whence it passes to the slidevalves e and f through pipes 9 and 10, Figs. 3 and 4. The gaseous mixture after having acted upon the driving-pistons b and c passes out through the exhaust-pipes 11 and 12. All parts which are subject to radiation are preferably jacketed or covered with non-heat-conducting material, which is not represented in the drawings-nor are the safety-valves and other accessory parts-in order to simplify the drawings.

The generatingcylinder or compressor, which in the example of the drawings is represented as placed above the driving-cylinders, may of course be arranged in any other suitable manner, and especially on one of the sides, according to requirements, While, however, surrounding all cylinders with one and the same gas and steam reservoir. The economy of this construction lies in the fact that a large portion of the heat may be utilized which is set free by the explosion, first, by reducing more or less the richness of the explosive mixture by the addition of steam and by increasi ng in proportion the compression of the mixture in order to obtain a good combustion, and, second, by producing and superheating steam in a suitable quantity, the action of which unites and combines with that of the gases, while at the same time reducing lthe temperature of the walls and of the apparatus generally to a degree compatible with the proper working of the constituent parts.

I claim- 1.l In a compound generator and motor, the combination of a compression and explosion cylinder having a valved inlet for an explosive mixture, a reservoir for the gases of combustion, a valved connection between the cylinder and reservoir, spiral passages around the cylinder, one of said passages being adapted to conduct steam so as to mingle with the gases of combustion and the other to conduct the gases of combustion from the reservoir, and means for leading off the mixed steam and gases of combustion for use, substantially as set forth..

2. In a compound generator and motor, the combination of a compression and explosion cylinder having a valved inlet for an explosive mixture, driving-cylinders, a reservoir for the gases of combustion, a tube connecting the explosion-cylinder with said reservoir, an automatic valve for said tube, a spiral passage around the explosion-cylinder for conducting steam to said tube, another spiral passage around the explosion-cylinder, connected with the reservoir by means of a tube, and serving to lead olf the mixed steam and gases of combustion, a distributing-chamber to which the last-named passage leads, pipes leading from the distributing-chamber to the driving-cylinders, and valves controlling said pipes, su bstantially as set forth.

3. In a compound generator and motor, the combination of a compression and explosion cylinder having a valved inlet for an explosive mixture, a reservoir in which the gases of combustion are forced for use, a suitable connection between the cylinder and reservoir, a diferential automatic valve controlling the passage through said connection, a pressure device for retaining said valve on its seat, and a counter-pressure device for removing the tension of the said pressure device, whereby said valve is adapted to be retained on its seat by the gas-pressure, silbstantially as set forth.

4. In a compound generator and motor, the combination, of a compression and explosion cylinder having a valved inlet for an explosive mixture, a reservoir into which the gases of combustion are forced for use, a suitable connection between the cylinder and reservoir, a differential automatic valve controlling the passage through said connection, a pressure device for retaining said Valve on its seat, a Siphon connected with said reservoir and containing a liquid, and a piston in said Siphon, acted on by said liquid, said siphon and piston serving as a counter-pressure device acting on said pressure device for removing its tension from said valve,whereby the valve is adapted to be retained to its seat by the gas-pressure, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
